Relative risks for the incidence of (A) stillbirth; (B) preterm birth; (C) gestational hypertensive disease; and (D) low-birth weight for the combined cohort. Relative risks with corresponding 95% CI and p-values obtained from modified Poisson approach with a sandwich estimator for each categorical outcome and 5-degree Celsius change in trimester average daily maximum temperatures. Models include site and site by outcome interaction. Site-specific relative risks were derived from the site by outcome interaction and are presented in supplementary figures.
